    * tree-ssa-math-opts.c (bswap_replace): Construct gsi from cur_stmt
    rather than taking it as a parameter. Add some comments to explain the
    gsi_move_before in case of load and why canonicalization of bswap into
    a rotation is only done for 16bit values.
    (pass_optimize_bswap::execute): Adapt for loop via gsi to make gsi
    refer to the statement just before cur_stmt. Ignore 16bit bswap that
    are already in canonical form. Adapt bswap_replace to removal of its
    gsi parameter.
